A special edition of Deal or No Deal? (2005) with the stars of 8 Out of 10 Cats (2005). '8 Out of 10 Cats' and '8 Out of 10 Cats Do Countdown' host Jimmy Carr takes over as guest host while '8 Out of 10 Cats' and '8 Out of 10 Cats Do Countdown' regulars Sean Lock and Jon Richardson team up to beat the banker and win some money for their charities of choice. Sean's bulletproof strategy fails them immediately, so the banker pressures Jon into taking the offered lowball sum before they loose all the big money. Will he give in to pressure? The box keepers include Sean's friends, Jon's friends and former flatmates, a star of The Only Way Is Essex, the co-hosts of 'Countdown' and '8 Out of 10 Cats Do Countdown' Rachel Riley and Susie Dent, former winners and losers of 'Deal or No Deal' as well as several other members of '8 Out of 10 Cats' guest lineup. Another Cat, Joe Wilkinson, gets to be the Banker's Assistant but immediately becomes drunk with power.
